Speedy22 [email protected] Introduction
Most of the information was based on the top and bottom layers of a dechipped 360 motherboard and decapped chips, I will update the information once I gain full knowledge of the inner layers of the motherboard. For reference, I have also included some information I have gathered from images of Development Hardware and XDK hardware found on the net. Please double-check my information, I am human and I do make mistakes. I have also attempted to give credit where credit was due. If you find any errors or omissions, please let me know so that I can correct it on future versions. Like most, I am doing this as a hobby in my spare time, so I will do my best to keep the information up to date but I can not make any guarantees.
I am currently looking for a supplier/manufacturer for the following components;
Controller Headset Port Both the Male and Female Connector.
Memory Card Port Male Connector (On Memory Card)
RF Module Port Male Connector (On RF Module)
Hard Drive Port Male Connector (On Hard Drive)
My current employment position will be changing in the near future, so I will be open for new opportunities. I am a Canadian citizen living in Waterloo, ON, Canada with a background in Electronics Engineering and Management. Feel free to contact me for more details.

Power Supply is difficult to open up. I would not recommend it. 1) Remove rubber feet (they are glued in place). This will probably destroy them. 2) Dig out all the glue, including the glue in the head of the philips screws. 3) Remove the 4 screws. 4) Remove bottom cover. 5) Remove the two philips screws. One on each side of the heat sink. 6) Gently wiggle circuit board out of the top cover. The DC supply side should lift up first. Heat sink grease is preventing the easy removal of the circuit board. Continue to wiggle the circuit board until the grease bond is broken.
6 J9A2 XDK DC Power

Note: This connector is used to supply power to the extra circuitry used in the XDK (motherboard version 009). The circuitry is located in the "Sidecar" that attaches to the hard drive side of the xbox 360.

28 System Requirements
Absolute Minimum
Motherboard, Power Supply (12 volt 16amp, 5 volt 1amp), Video Cable, and a momentary pushbutton switch (for power on/off).
I have tested this with dashboard 1888 and 2241. A dashboard update could change this.
Absolute Minimum to play games or DVDs
As above, but subtract the push button and add the DVD player and a wired controller.
Absolute Minimum to play just DVDs
As above, but the remote can be used instead of the wire controller.
Remember that this could change with a dashboard update.
29 Retail
Note: Flash Bios Version 2.0.1888.0
30 XeDK
Note: Appears to be a final version of the XeDK. Flash Bios Version 2.0.1839.2 Also known as XDK. Used in conjunction with the SDK (Software Development Kit). Most likely, the XeDK is also connected to a network with various PCs running SDK.
